CLEANING DEVICE.

Application filed January 27, 1921.

' have invented a new and Improved Cleaning Device, of which the following is a full, clear, and exact description.

My invention relates to a cleaning device, and aims to provide an element of this nature, particularly adapted to clean brushes.

It is a well appreciated fact that it has been cutstomary, in connection with brushes, to provide elements in the nature of combs, the teeth of which have been passed through the body of the brush, for removing foreign matter, such as hair, etc from bristles of the same.

Thiscleaning action has beennecessarily limited, particularly when hair, dandruff, etc., was to be cleaned from the brush, in that these foreign elements have been intwined and in intimate contact with the bristles.

Vith this in view, I have constructed a cleaning device, and an object of my inven tion is the provision of. an element of this nature in which all foreign matter will be effectively removed from the bristles of a brush.

A further object of my invention is the construction of a cleaning device in which it will not be necessary to exert as much force to clean the bristles, as has been heretofore necessary, so that the wear upon the body of the brush, incident to this action, is reduced to a minimum.

Another object of the invention is that of providing a device of the character stated, which shall be extremely simple in construction and operation, so that the same may be placed upon the market at a minimum figure, and be free from mechanical troubles.

Other objects of my invention will appear in the annexed specification and drawings, which latter present one practical embodiment of the same, and in which Figure 1 is a sectional side view of a cleaning device constructed in accordance with my invention.

Figure 2 is a sectional plan view of the same taken along the lines 22 and in the direction of the arrows indicated in Figure 1.

Figure 3 is a sectional end view taken Specification of Letters Patent.

along the line 33 and in direction of the arrows also indicated in Figure 1, and

Figure 1 is an enlarged fragmentary sectional view of one of the details of my invention. v

Referring now more particularly to Figures 1 and 2, it will be seen that my device preferably includes a casing 5 upon the upper face ofwhich supporting brackets 6 may be affixed, said supporting brackets being adapted to engage and retain a brush 7 of any desired type in applied position thereon.

It will also be noted that the upper face of the casing 5 may conveniently provide a series of longitudinally extending slots 8 which under lie the bristles of the brush 7. Also a series of cleaning elements 9 are positioned within the body of the casing 5 and provide teeth, which latter are curved and extend through the slots 8, in the upper face of the casing 5.

With a view of actuating the cleaningelee ments 9, whichcorrespond in number to the number of slots 8 provided, I preferably mount the same upon a shaft 10, which latter is provided with gears 11 adjacent its endvportions, these gears being engaged and supported by tracks in the nature of serrated bars 12. 1 y

Thus it will be obvious that upon a rolling contact being established between the gears 11 and bars 12 that the shaft 10 and cleaning elements 9 carried thereby will be caused to move longitudinal of the casing 5, and at the same time, the cleaning elements will be rotated. Now with a view of providing means serving to accomplish this movement, I preferably utilize an endless member in the nature of a sprocket chain 13, which passes around gears 14L rotatably secured adjacent the ends of the casing, and a rack 15 engaging a gear 16 mounted upon the shaft forming a supporting element for one of the gears 14 will serve to effect a movement of the chain 13 upon the same being projected or retracted.

Suitable means for accomplishing this latter motion are provided by utilizing a handle 17 secured to the outer end of a bar 18 forming a continuation of the rack 15, and a spring 19 co-operating with the handle 17 and bar 18 serves to return these elements to their normal position subsequent to the handle having been depressed.

Thus it will be seen that upon the handle fl? being projected. downwardly, that the rack will cause a movement of the chain 13, and this element being coupled to the shaft 10, asby means of the bearing 20, it will be obvious that the shaft 10 will be moved longitudinal of the casing 5, which by virtue of the motion aforedescribed, will result in a rotation of the cleaning elements 9, and a consequential co-operation between these elements, and the bristles of the brush 7 it being noted that the handle 17 upon being released will return to its normal position by virtue of the connection of the spring j 19", this insuring a return of all of the parts to their initial position.

Fromthe foregoing it will be appreciated that I have constructed a cleaning device, more particularly adapted for use in connection with all classes of brushes, but more particularly for use in connection'with the cleaning of hair brushes, and it will be ob vi'ous that by means of the structure described, that these brushes maybe cleaned in a most desirable manner, and w1th1n a I minimum space of time, which is to be particularly desired, where the device is utilized in barber shops.

It will also be understood that numerous modifications of structuremight readily be resorted to without in the least departing from the. spirit of my invention, which I claim as:

1 A cleaning device including a casing formed with openings, cleaning means w1thlnsaid casing and extending through'said openings, and means for actuating said cleanlng means and bemg adapted to movesaid cleaning means longitudinally and rotatably with respect to said casing for enslots, and means for moving said shaft upon the tracks and in rolling contact there with. i

4. A cleaningdevice, including a casing provided with slots in one of its walls, a shaft positioned within said casing, cleaning elements mounted upon said shaft and extending through said slots, gears secured to the ends of said shaft, tracks presenting serrated upper edges adapted to be engaged by saidgears, and means for moving said shaft along said tracks.

5. A cleaning device, lncluding a casing provided with slots in one of its walls, a shaft positioned within said casing, cleaning' elements mounted upon said shaft and extendingthrough said slots gears secured to the ends of said shaft, tracks presenting serrated upper edges adapted to be engaged by said gears, an endless member within said casing and attached to said shaft, and means for moving said endless members.
